In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Q: Article: Research has shown that 85 percent of communication is nonverbal, so choosing what to wear to an interview is clearly an important part of your overall presentation. It won't make up for weak answers, but it can communicate some positive things about your personality and what you might be like to work with.  * Blue: You can't go wrong with darker shades of blue, especially navy. Choosing from this powerful color1 will project an image of someone who is in control. From the interviewer's point of view, the color1 blue suggests calm, stability, trust, truth, confidence and security. These are all great messages to send without saying a word.  * Gray: After blue, gray is the second most popular color to wear for an interview. Like darker blue, it's not a distracting color1 to the interviewer, which means they'll be focused more on what you're saying and how you're saying it. Gray means sophistication  , so use it to your advantage.  * Black: This is a commanding color1 and represents authority. Black also suggests excitement, so use it carefully when putting together your interview outfit. You may want to use it as an accent   --like in a scarf or tie, for instance--rather than as the primary color.  * Red: This is an extremely powerful color1. It's so strong that you should only use it as an accent color1. Reds are associated with energy, passion, desire, power and aggression. People think of intensity   and passion when they see the color1 red, so use it carefully or it could send the wrong message to the interviewer.  * White: White shirts and blouses are always appropriate. It sends the message of simplicity, cleanliness, precision and goodness.

Q: Article: A car that runs on coffee is unveiled(shown to the public for the first time)today but at between 25 and 50 times the cost of running a car on petrol, the invention won't please any motor industry accountants. Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for PS400 and it was chosen because it looked like the time-traveling DeLorean in the movieBack To The Future.The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules  .It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles. The team calculates the Car-puccino will do three miles per kilo of ground coffee   -- about 56 cups of espressos   per mile.The journey will use about 70 kilos of ground coffee which, at supermarket prices of between PS13 and PS26 a kilo depending on brand and quality, will cost between PS910 and PS1,820, or between 25 and 50 times the PS36 cost of petrol for the journey.In total, the trip will cost 11,760 espressos, and the team will have to take 'coffee breaks' roughly every 30 to 45 miles to pour in more granules.They will also have to stop about every 60 miles to clean out the 'coffee filters' to rid them of the soot and tar which is also generated by the process.So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours. Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty's Revenue and Custom haven't yet worked out how much. Nick Watson, producer of Bang Goes The Theory, said, "Coffee, like wood or coal, has some carbon content so you can use it as a fuel.The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns.The brand doesn't matter." He said the same technology could be used to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste. 
 Answer: It should be very dry.

A: Which is the right way to choose the coffee used as fuels to run the Car-puccino?

Q: Article: A good friend of mine lives about one hour away. I called her last week and found out that she wasn't doing well at work, which would make the following year a little more difficult. After hanging up the phone, I decided to offer to help her, but I couldn't think of what to do. However, opportunities come themselves when you're not even looking for. A few days later, some friends and I happened to be eating desserts at a restaurant in her city. As we were looking at the menu, I turned to my friends and asked them if they wanted to join in a game. After explaining the idea, they decided to take 15 minutes to _ . We ordered an extra dessert, wrote a note, added a smile card and were off. However, there was one problem: I had no idea where she was. Therefore, it was time to rely on the network. I called up a friend and got him to call her to see what she was doing and found out that she was at work. We drove to her work place and one of my friends became the delivery person.He went in to look for my friend, found her, didn't really answer her questions and walked out, saying he's simply a delivery person. He ran out quickly and I bent down as we drove by to make sure she didn't follow him out. Afterwards, all of us had this huge smile on our faces. We felt as if we had just planned a surprise party or something. A simple opportunity turned into a moment that many of us can now share. 
 Answer: Because she failed a test.
